Abstract
A system for harvesting footwear energy. The energy may be in a form of footwear movement which involves a compression and decompression of chambers situated in the footwear. There may be a back chamber in the heel area and a front chamber in the toe area of the footwear. The chambers may be filled with gas which moves in and out upon compression and decompression of the chambers at the heel and toe areas upon the ambulatory motion of a person wearing the footwear. The moving gas may go through a pneumatic rectifier that provides a unidirectional stream of gas to spin a micro-turbine which turns an electrical generator, or operate a pneumatic device.
